Suggestion: `qse add <args>` command

[IAmRiteshKoushik]

Proposal

A user may start with a particular template but then feel like extending it. A basic express template can be extended with a Postgres, MySQL or Redis as an add-on. In such a scenario, it would be helpful to have the add function which can bring forth some boiler-plate and associated folder-structure to the repository.

Potential set of add-ons:

1. SQL Databases
2. NoSQL Databases
3. Socket.io (or) ws
4. Redis
5. ORMs
6. Kafka

Can I take this up?

[Ashrockzzz2003]

Yes
but we need to have a clear idea on how the experience is gonna be for the user.
Come up with a flow. Once we finalize that, we'll move to implementing it

First, I will rename variable and file names will be updated to follow a consistent naming convention.

When user enters command qse add <template1> <template2> ...,

• .env, package.json, appConfig.js, initLog.js, index.js will be automatically updated. Conflicting variable names will be resolved by appending its template name before the variables.

• Folders with same name are moved into sub-folders with template name appended to their name. These are put under a folder with the original name. eg. mysql: router/sampleRouter.js and mongo: router/sampleRouter.js become router/router_mysql/sampleRouter.js and router/router_mongo/sampleRouter.js.

• Imports will be fixed based on the new file layout.

• index.js and initLog.js will be combined with their content arranged to make sense logically.

• Conflicting routes will be fixed by prefixing the routes with the template name in index.js

• List of all changes will be shown to the user after completion.

I am not sure we need any user interaction at all.
Maybe we can provide an option to install/not install the new template's dependencies.
